Web Hosting Talk : Web Hosting Main Forums : Hosting Security and Technology : Quick question about setting up my name servers

[hostlyon]

Heyy ,

is it possible to use one IP address for both name servers. For Example

ns1.yourdomain.com - 193.174.32.18
ns2.yourdomain.com - 193.174.32.18

Sorry for the stupid question .. im a newbie at this. Thanks

Yes, but there isn't really much point in it because the second name server is designed to be on another IP to increase redundancy. ie if the first IP is unavailable, the second can be used.

Hope that helps,
Mike

yes you are right... im just making sure... so I would have to get a second IP address from my ISP to add a second ip address for the name server?

You wouldn't *have* to. But it would help. You could run both name servers off the one IP address, but like I said, it's designed with redundancy in mind.

Hope that helps,
Mike

Mike thanks for the info!

There's not much point adding a second IP to the same nameserver server either. The idea is two have two or more seperate nameservers.

Usually you can just up the IP by one and it will still trace to the same server.

x.x.x.001
x.x.x.002

Not if it's not your IP.

last question ... in the initial set up of centos 5 it gives me an option to enter in an ip address under the ipv4.. What is that IP address for?

Here is an snapshot to show you what im talking about

Thank you very much for your help!

That would be the LAN IP (local area network)

Dan_EZPZ,
Sorry i could not understand what you said. Usually the two name servers are having different IPs I think. And it is to make sure that one works even if the other one is down by some reasons. Am I right?
